Description
The Infinite Resistance block represents an infinite electrical resistance that draws no current. Use this block to set the initial voltage difference between two electrical nodes without affecting model equations. To do this, use the Initial Targets section in the block dialog box and set the priority and initial target value for the Voltage difference variable prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.
Variables
To set the priority and initial target values for the block variables prior to simulation, use the Initial Targets section in the block dialog box or Property Inspector. For more information, see Set Priority and Initial Target for Block Variables.
Nominal values provide a way to specify the expected magnitude of a variable in a model. Using system scaling based on nominal values increases the simulation robustness. Nominal values can come from different sources, one of which is the Nominal Values section in the block dialog box or Property Inspector. For more information, see Modify Nominal Values for a Block Variable.

Programmatic Use: Add Block
To add the block programmatically, use the add_block function with one of these library block paths as the source.
"fl_lib/Electrical/Electrical Elements/Infinite Resistance"
Example: add_block("fl_lib/Electrical/Electrical Elements/Infinite Resistance","myModel/myBlock",MakeNameUnique="on")
For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
